As the title suggests, I came up with this in a dream, so it's bound to be very, very unbalanced, for better or worse.
It's a mafia support role called the "octolizer" which can twice a game completely wipe a person's role. Essentially, the octolizer is a mafia brain surgeon, but his brain is so big that he dies of brain cancer every other night (or every full moon) if he does not vote innocent at least once.
The person octopus'd will have their role wiped, and they will be essentially reverted to old used-up retributionist.
No, I don't get it. It was a dream, what do you want
